Drops 'const' qualifier

Getting the following error:

/Users/amallia/Development/sera/external/tqdm.cpp/include/tqdm/utils.h:106:12: error: binding value of type 'const std::__1::iterator<std::__1::forward_iterator_tag, ds2i::binary_freq_collection::sequence, long,

if you remove tqdm::tqdm from the last line (leaving input unwrapped) does it work?

Yes. Of course

This is the iterator:

        class iterator : public std::iterator<std::forward_iterator_tag,
                                              sequence> {

if I change it like this it works:

        class iterator : public std::iterator<std::forward_iterator_tag,
                                              const sequence> {

But i feel there is also a bug in tqdm
